Introduction: Adrenal insufficiency (AI) is a rare and potentially life-threatening disease. The most common causes are primary adrenal insufficiency (Addison’s Disease), due to an adrenocortical disease, and secondary insufficiency, due to disorders of the pituitary gland. Chronic glucocorticoid replacement is vital and patients should be educated about how to act in acute stress situations, in order to avoid adrenal crisis. Taking this into account, we organized educati...

Introduction: Adrenocortical carcinomas are rare neoplasms with an incidence of 0.7 to 1.5 per million/year. Diagnosis often requires a multidisciplinary approach. When the disease is confined to the adrenal gland, absolute criteria defining malignancy, do not exist, however a score of Weiss> or =a 3 is considered diagnosis. The prognosis is usually reserved and conventional chemotherapy is not curative.Material and Methods: Retrospective analysis of...

Background: Distal symmetric polyneuropathy (DSPN) is one of the most prevalent chronic complications of diabetes and the most common cause in the pathway to diabetic foot ulceration. Screening for DSPN enables early intervention and prevention of complications. The Semmes-Weinstein Monofilament Examination (SWME) is currently the method of choice to screen DSPN, but ideally two neurologic tests should be used. The Michigan Neuropathy Screening Instrument (MNSI), which evaluat...

Introduction: Congenital hyperinsulinism (CHI) is a heterogenous disease caused by insulin secretion regulatory defects, being ABCC8/KCNJ11 the most commonly affected genes. It can present as focal or diffuse pancreatic disease, which is mainly determined by the genotype. Diazoxide is the first-line medication in diffuse cases, however many do not respond satisfactory. Second-line options include somatostatin analogues and surgery, which is curative in case of focal CHI.<p...

Introduction: Graves’ disease (GD) hyperthyroidism is caused by autoantibodies against TSH receptor (TRAb). Three varieties of TRAb are now recognized: stimulating (TSI), blocking and neutral antibodies. Current TRAb immunoassays detect and quantify serum immunoglobulins that interact with the TSH receptor but without discriminating their function. An automated immunoassay for the detection and quantification of TSI is available.Objective: Our study...

Case report: 66 year old male with a neck growing mass performed an ultrasonography and fine-needle aspiration biopsy which was suspicious for papillary carcinoma. The patient was submitted to total thyroidectomy and central and left lateral compartments lymph node dissection. The histological report showed a follicular carcinoma of 9 cm, with multiple lymphovascular invasions and skeletal muscle invasion. There was a focally positive surgical margin and resected lymph nodes h...

Background: Papillary thyroid cancer (PTC) is the most frequent type of well-differentiated thyroid cancer (WDTC) and frequently poses a management dilemma. Its indolent behavior associated with high long term survival support the trend towards a more conservative management approach. The authors present a case of isolated bone metastases as the form of presentation of papillary thyroid carcinoma. A 61-year-old man was admitted with complaints of lower back pain for the previo...

Introduction: Insulinomas are the most frequent cause of endogenous hypoglycaemia. 90 to 95% of these are benign. Surgical enucleation or resection is the standard treatment. Medical therapy focuses mainly on the use of diazoxide with few alternatives in patients with high surgical risk.Case-report: Female patient, 89 years-old, non-diabetic, with previous history of acute myocardial infarction, stroke with motor sequelae, pacemaker carrier and severe ao...

Introduction: The diagnosis of infected ulcer is mainly clinical. The goals of the microbiological studies are identification of the pathogen and evaluation of susceptibility to antibiotics to minimize exposure to drugs and selection of resistant strains.Methods: Retrospective cohort study; Data collection: 1 January 2010 to 31 December 2014. Were included wound samples of aspirate, nonsurgical/surgical exudate, pus from abscesses and bone fragments from...

Introduction: The complications related to ulcerated foot lesions are a common cause of hospitalization among diabetics. Diabetic foot infection is associated with high morbidity and is the most common precipitating factor to precede amputations of the lower limbs.Methods: Retrospective, cohort study; were included 200 patients from the Diabetic Foot consultation of the Endocrinology Department between 1 January and 31 August 2015. Ulcerated lesions were...
